2. Burr grinders

While blade grinders are very inconsistent with the size of your grounds, a burr grinder can give you the uniform appearance you're looking for.

They aren't much higher-priced from a blade grinder either. In addition, a burr grinder can give you more control over the speed of your machine, especially when you consider that some burr grinders are still hand-crank style instead of electric.

This key difference also means that the chances of your coffee beans burning are greatly reduced.

Blade vs Burr: Which is better for Keurig Reusable K Cup Filter?

The blades of a burr grinder differ from those of a blade grinder in that a blade grinder has a single blade in the middle of the machine, similar to what a blender looks like.

This is what's to blame for the inconsistency in the grounds. On the other hand, the burr blades form a sort of sandwich around your coffee beans.

There is one below them and one on top and they crush and grind the beans to create that uniform shape.

The distance between the blades can also be adjusted, depending on your machine, to give you a finer or a coarser grind.

Manual vs Electric: Which is better for Keurig Reusable single cup Filter?

As far as knowing whether you need a manual or electric burr grinder, it really depends on your goals, where you will be placing the machine, and your budget.

Typically, a manual is less expensive than an electric machine, but this also means it may take a little longer to grind your coffee.

The manual machines are also smaller, which can be good if you are limited on space, such as in an office or apartment kitchen.

Electrical grinders are more expensive, but they are more likely to do a better job of grinding the coffee beans.

In the next section, we will look at the best coffee grinder for Keurig filters.

4. Rancilio HSD-ROC-SD Rocky Espresso Coffee Grinder

The Rancilio Rocky Espresso coffee grinder is the most expensive machine on this list, but the stylish design and capabilities help make up for it.

This machine is also much taller than the others listed, and weighs close to 16 pounds. This is not a good choice for those who would need to move the machine often (if they have limited counter space).

One bonus feature of the Rocky grinder is that it has a fork mounted on the front of the machine that allows you to grind directly into the filter for your coffee machine.

It also has two power switches, one for the main power and one to actually start the grinding process.
